Hi All,
Facing an issue with knox gateway.
When we pass a url like:
https://app1.company.com:9443/company/opt/opentext/common/jslib/themes/default/athena.css;jsessionid...
The rule urlencodes it before sending to tomcat server. Tomcat then throws not found error:
I have two questions on this:
1. Is there a way to tell the rewrite rule to not encode the url or is there another way to not encode the incoming URL before forwarding to tomcat server?
I noticed ‘;’ and ‘=’ are getting converted in their ASCII formats.
;jsessionid= à %3Bjsessionid%3D
And the url passed becomes:
http://ip-172-1-1-1:9090/opentext/common/jslib/themes/default/athena.css%3Bjsessionid%3D6F4614AEAE08...
2. We were trying to specify another dispatch (PassAllHeadersDispatch) in the service.xml
But it never gets picked up as shown in the debug logs. How can we change the default dispatch apart from putting in the service.xml?
We did checked that the PassAllHeadersDispatch are supported in the knox version (0.9) we are using.
Given below are the topology, service.xml, rewrite.xml and the relevant portion of the log.

Appreciate your help and time.
